To all whom it may concern:

Be it known that l, JOSEPH ld. PERRY, a citizen of the United States, residing at Wilkes-Barre, in the county, of Luzerne and 'State of Pennsylvania, have invented ce1 tain new and useful Improvements in Devices for Distilling llVater; and I do hereby declare the followin to be a full, clear, and exact description ot the invention, such as will enable others-skilled in the art to which .it appertains to make and use the same.

The object of my invention is to distil water by converting it into steam of avery low temperature, and I'vaim to provide a mechanism which may conveniently be at,- tached to-any boiler containing hot and cold water, vwhich mechanism is combined with cold Water boiler; Fig. 2 is a top plan View of the retort and the heating-chamber; Fig. 3

is an enlarged detail viewl of the means of attachment with the boiler of the hotfwater pipe supplying the retort; ,Y

Referring in detailJ to the drawing, A; des ignates a' boiler of ordinary construction, and B the cold water pipe and its connections With the boiler, having a pipe C conveying cold Water nearly `to the bottom of the boiler.

.From the top of the boiler extends the usuaifhot-water pipe D, Whichconveys h'ot water to all parts of a building.

On the bottom of boiler A is the coldwater pipe E running to the water-back of the ordinary range, also the returning hot- Water pipe F and its connections coming from the range to the boiler.

.For sustaining the Weight of the distilling-device, a strap of iiat iron G is passed around the boiler in two haltl sections and bolted and drawn together'.` It has 'exten sions running out from the boiler to form a base or support for the still. Upon this eX- tension is placed a suit-able plate or bottom- H, secured to the extension. Upon the bot tom or plate7H is secured a heatschamber I, in which is placed a 'gas-fixture J, or the like, at the bottom of which is the usual Bunsen gas-burner, having a 'pipe4 J attached to the gaspipe of the house. This chamber I is Without air-openings near the flame, but has them near its base, by which means thel heat is more confined in acting against the bot tom of a water-chamber K, the sides of which converge downward and extend into the heatrhamber I. The heat-chamber I is desirably formed interiorly with top grooves z' (Figs. l and 2) for outlet of heat. It will thus be seen that the products of combustion, before escaping, lhave to travel upward around the sides of retort K., thus more.

quickly vaporizing the 'water therein, and effecting a conservation of heat. 'If no chamber I were provided, the heat would Waste b y spreading out horizontally.

Upon the retort K is a steam-chamber L. This chamber is formed, by means of an arched condensingsurface m and a flaring, open-ended hood ic removably secured to the top of chamber K. Thus steam escapes through the open' end of hood candstrikes the hipped surface m of the chamber L.

Above the steam-chamber L is a `cold- Water vessell N, which acts asa condenser upon the steam striking the under surface of the arched plate fm..

The cold Water to supply the chamber N is taken from the water-pipe B leading` to the boilerv by means of a pipe O, having a valve P. This cold-water pipedischarges close upon the conical portion of the steamchamber L. i p

From the cold-water chamber N and on the opposite side from the pipe Ois another pipe Q leading the Water from or throu h chamber N and discharging it into the boi e1' A :it the same distance rom its bottom as the ordinary cold-water pipe` B.

Within the Coldwater chamber N and from the conical portion of the steamchamber, extends into the cold Water a steam* pipe'R, to which is attached a coil of lead or other pipe S, which leads back to the steam-chamber L. This pipe and coil or .sirable to" provide means forvcooling the same. I referably provide a pipen, which may be disposed near the to of vessel N, and which has its outlet-end 1n line with a vertically-disposed cold-water ipe n2# pro- 5 vided at its end yvith an out et-spigot n3.

Communicating with pipe Z is a pipe Z2`disposed Awithin the cold-water pipe n2 and leadin to a catch-receptacle, such as a can 3. W en the machine is in use, there will 1o be a constant How of cold water through the vessel N by means of the supply-pipe'O, spigot n, plpe n2,'and pipe n3, and the hot water of condensation, as it passes through the pipe Z2, will be Very appreciably cooled.

' The chamber K is supplied with water from the boiler A near its top bynieans of a stop-valve u and, pipe T, and also by means of a valve v attached to 'that part of pipe T which enters the hot-water chamber.

The regulation of the required amount of water from boiler A through pipe T and valve u is effected by an automatic device acting within water-chamber K, as follows: Within chamber K is a hollow ioat W, to

the upper end of which is secured a hollow brass pipe passing through a brass pipe Y, which is threaded into the upper central portion of the surface m and is also secured to the cover Z, or top of the cold-water chamber N. In order to be secured againstleakage on account of the cold-water pressure, this rod Y has a stuffing-box I surrounding the said pipe Y and by suitable packing may be made water ti ht.

Upon cover Z 1s securely bolted the stud 2; attached thereto is a lever 3, slotted at the end to allow rod to slide and maintain its position without friction in .acting upon lever 3.

40 Attached to lever 3 at the other end `is a rod 4, which, in turn, is secured to thelever of the stop valve a.

As a convenient means of attaching the pipe 'I to the boiler, I have devised the folowing construction: 5 is a casting formed with a rim, 6, and an internallyhreaded extension or boss 7, through which the pipe T passes, as shown.- Bolts 7 X extend from the interior of the boiler through the same and through the casting 5. Nuts 8, 8 are secured on the bolts to draw the heads of the bolts tightly against the boiler; and, on the ends of the bolts are secured additional nuts 9, 9, to maintain the casting firmly against the boiler, as shown. Admission to the boilerto place the bolts in position is afforded by means of the opening' 10 throughthe `ooilershell. This opening may be closed by a cap 11, or any other desirable means. Hydraulic cement, or the like, 12, is finally disposed.

in the space between the interior of the boiler and the casting 5, which cement sets to form a water-tight joint at this place.

The operation of the automatic device is as follows: When the heat and steam or iow I. therefore close the sto oi? hot water from boiler A rises above-the proper level, the water will act upon the hollow iioat W and raise it upward, whichcauses the lever 3 to moveup at the slotted end and press the rod L vdownward, actin ,c ;,70 thereby to close sto ,valve-u andcheck the flow of water from oiler A, and, asv soon as the water has been vaporized and condensed, the oat W will immediatelydescend and reopen the stop valve u to allow the infiow of' '7.5 water and produce an equilibrium of pres` sure. The small valve e may be used to regul ate the exact amount of water required to maintain .a regular, steady and uniform operation of the device, or may be changed arbitrarily at will to increase or diminish the amount of water in chamber K.

It will be observed that great economy of the heatrequired to Vaporize the water is accomplished by taking thehot Water directly from the. top of boiler A, as it is al ways in a state approaching 212o F. and often contains a large proportion of actual steam ready toy be condensed into pure water.

It will be seen, also, y'that when the flow 0h90 .Y

cold water is required to lill the chamber N and to operate this machine for the purposes '-named, there will be no necessity to allow the water from pipe B to flow into boiler A.l

valve 13 on pi e 95 B and open the stop-va Ve l), and there y it will be -seen thatthe same flow of cold water through chamber N by means of pipes O and Q, on the outside of the boiler will v act in the same manner as when the cold water i's put into the boiler b means of the inside pipe C. The only di erence will be slight change in the temperature of the Water, which has become slightly warmer," so that not a particle ofkheat has been lost.' 105 As all .the dirt, filth, germs, and other. chemical impurities will be precipitated to the bottom of chamber K, it will be necessary to clean it out occasionally and for this purpose the mud-spigot 412 is connected near the bottom, and by opening it the'force -of water issuing from pipe T may be used to run clean water, when favorable, and clean it out. Readily to dislodge sediment collecting upon the bottom of chamber K, I'have 115 provided a scraper K- disposed in chamber K, the handle ZF of which extends through the Awalls of chambers K and I and through an exteriorly threaded boss or lug Ka on the outside of chamber I. Screwed on the lug is a cap 7a4, thus making a Water-tight connection at this point. Without limiting myself to details of construction, what I claim as new and desire to secure by`Letters-Patent is: l

The combination with the usual hot-water boiler connected to the water-back of a stove, or the like, of a ret-ort communicating divrectly with the boiler, whereby hot :vater is supplied directr to said retort, a condensingelmirlber disposed above and communicating with said retort, and provided, i1'1termediet-e its depth and spannmg its width, with zu] arched condensmg Surface, whereby Saud d vchamber is divided into au upper and a lower compartment; a stean'1'- ondeus1ng coil the upper compartment and provided wlth 'am inlet-end conimumcatiug with the lower compartment und with an outlet-end l l l l l l l also communicating with said lower pertinent. v
